The 71M6545HT-IGT/F is a metrology processor designed for three-phase residential, commercial, and industrial energy meters. It integrates a 22-bit delta-sigma ADC, a customizable 32-bit computation engine, and an 8051-compatible MPU core with 64KB flash and 5KB RAM.
Key features include 0.1% typical accuracy over a 2000:1 current range, exceeding IEC 62053/ANSI C12.20 standards. It supports four-quadrant metering and operates over a 46-64Hz line frequency range with the same calibration. The device includes an SPI interface for host communication and an optional MPU core for data capture and preprocessing.
This energy meter IC comes in a 64-pin LQFP package and is designed for surface mounting. It operates within an industrial temperature range of -40°C to 85°C. The device also integrates an RTC, DIO, and UART for various communication duties.
